LYMPHATIC SYSTEM AND IMMUNITY. Lymph organs include the bone marrow, lymph nodes, spleen, and thymus. Bone marrow contains tissue that produces lymphocytes. B-lymphocytes (B-cells) mature in the bone marrow. T-lymphocytes (T-cells) mature in the thymus gland. Other blood cells such as monocytes and leukocytes are produced in the bone marrow. Lymph nodes are areas of concentrated lymphocytes and macrophages along the lymphatic veins.

Immune Organs - organs of the immune system The lymphatic system consists of two parts, the primary and secondary organs. The thymus gland (located beneath the breast bone, and functioning at its peak during adolescence) and the bone marrow produce specialized lymphocytes—T-cells and B-cells and dispatching them through the lymph vessels to the secondary organs.o, the bone marrow creates the stem cells which become the cells of the immune system. Lymphocytes are sent from the bone marrow to the thymus gland to mature and are then stored in the secondary organs of the lymph system and in the blood stream.

Lymphocyte differentiation of lymphocytes. In the thymus, T cells multiply and differentiate into helper, regulatory, or cytotoxic T cells or become memory T cells. They are then seeded to peripheral tissues or circulate in the blood or lymphatic system.

Normal Structure, Function and Histology of the Thymus The thymus is a primary lymphoid organ, viz. bone marrow derived progenitor cells undergo differentiation/maturation, within the thymic microenvironment, to form the functional T cell repertoire. For an excellent overview of the functional aspects of the immune system one should consult: Abbas (2005), Brown et al.

Other Lymphoid Organs The thymus is a specialized organ of the immune system. It consists of primary lymphoid tissue, which provides a site for the generation and maturation of T lymphocytes, which are critical cells of the adaptive immune system. The thymus is of a pinkish-gray color, soft, and lobulated on its surfaces.

- The major parts of the system are the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils. Other organs, including the heart, lungs, intestines, liver, and skin also contain lymphatic tissue. gorhams.dk Lymphoma Is a disease in which malignant lymphocytes grow too fast or live too long.-lymphocytes (B-cells) mature in the bone marrow. T-lymphocytes (T-cells) mature in the thymus gland. Besides providing a home for lymphocytes (B-cells and T-cells), the ducts of the lymphatic system provide transportation for proteins, fats, and other substances in a medium called lymph.

Lymphoid tissue: T-lymphocytes and the Thymus It has an outer connective tissue capsule and septa. This organ is important for development of immunocompetent T-cells, proliferation of clones of of mature T-cells, developing immunological self-tolerance, and secretion of hormones for T-cell development.

How Blood Works Lymphocytes are complex cells that direct the body's immune system. T lymphocytes start in the bone marrow from pluripotent hematopoietic stem cells, then travel to and mature in the thymus gland. The thymus is located in the chest between the heart and sternum (breastbone). B lymphocytes mature in the bone marrow.T lymphocytes (T cells) are responsible for cell-mediated immunity. B lymphocytes are responsible for humoral immunity (antibody production). Seventy-five percent of lymphocytes are T cells. lymphocytes mature in the bone marrow.

Thymus The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, T cells mature. T cells are critical to the adaptive immune system, where the body adapts specifically to foreign invaders. The thymus is composed of two identical lobes and is located anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum. Histologically, each lobe of the thymus can be divided into a central medulla and a peripheral cortex which is surrounded by a

B-cells The B-cells mature in the bone marrow, while T-cells migrate through the bloodstream and mature in the thymus gland. B-cells help fight against bacteria and viruses that enter the body. They are able to detect and bind to specific foreign invaders (antigens) that enter the body.

Lymphatic system The lymphatic system consists of lymphatic organs, a conducting network of lymphatic vessels, and the circulating lymph. The thymus and the bone marrow constitute the primary lymphoid organs involved in the production and early clonal selection of lymphocyte tissues.ymphocytes are concentrated in the lymph nodes. The spleen and the thymus are also lymphoid organs of the immune system. The tonsils are lymphoid organs that are also associated with the digestive system. Lymphoid tissues contain lymphocytes, and also contain other types of cells for support.

Thymus The cortex and medulla play different roles in the development of T-cells. Cells in the thymus can be divided into thymic stromal cells and cells of hematopoietic origin (derived from bone marrow resident hematopoietic stem cells).Developing T-cells are referred to as thymocytes and are of hematopoietic origin.s the thymus is the organ of T-cell development, any congenital defect in thymic genesis or a defect in thymocyte development can lead to a profound T cell deficiency in primary immunodeficiency disease.

B Lymphocytes and Plasma Cells B lymphocytes mature within the bone marrow. Mature, naive B cells then migrate to peripheral lymph nodes, where they await B cell activation mediated by dendritic cells and CD4+ effector cells. Once in the circulation, they express a single, unique immunoglobulin (IgM).
